More ways to explore the area's outdoor wonders
You step out of the vehicle into a valley that feels carved from fire and ice: volcanic ridges flank grassy slopes, while braided glacial streams cut bright lines through black sand. The guide checks boots, points out a distant glacier tongue, and the group sets off—crossing shallow glacial rivers and climbing toward a ridge that opens into sweeping views of Þórsmörk (Thor's Forest).

History
Þórsmörk’s landscape was dramatically reshaped by volcanic eruptions and jökulhlaups; the 2010 Eyjafjallajökull event exposed new channels and an outlet glacier, Gígjökull.
Conservation
Stay on established trails to protect fragile vegetation and avoid creating new paths; glacial rivers and highland ecosystems are sensitive to erosion from off-trail travel.

Prepare for river crossings
Glacial rivers can be cold and swift; wear secure, waterproof boots and use trekking poles to steady yourself during fords.
Dress in layers
Bring a windproof shell, insulating midlayer and a breathable base layer—the weather can change rapidly in the valley.
Start early from Reykjavík
Allow extra time for the drive and vehicle river crossings; daylight and conditions determine how far you can hike.
Follow the guide’s route choices
Guides will alter the itinerary based on river levels and visibility—trust their local knowledge for safe passage.
Waterproof hiking boots
Stability and waterproofing are crucial for wet, uneven volcanic ground and river crossings.
Waterproof shell and wind layer
Protects against wind-driven rain and sudden temperature drops in the highlands.
Trekking poles
Helps with balance on river fords, scree and uneven terrain.
Microspikes or crampons
Useful in shoulder seasons or winter if snowfields and ice are present on the route.
